The organic approach to lawn care is based on the premise of maximizing natural resources and minimizing or eliminating any need for synthetic chemicals. Lawn care programs that use potentially harmful chemical fertilizers, pesticides, insecticides and herbicides pose health risks to humans, animals and plants. While these programs are designed to kill unwelcome insect pests or plants, chemical applications may unfortunately also be toxic to people, pets and desirable plant growth. The American Cancer Society and the Environmental Protection Agency (EPA) have jointly stated that 95% of the pesticides used on residential lawns are considered possible or probable carcinogens. A North Carolina research study in 1995 found a four-fold increase in soft-tissue cancers in children whose lawns were treated with pesticides. Research also suggests that use of the common herbicide 2,4-D doubles the risk of lymphoma in dogs. Some insecticides, such as the neurotoxin diazinon, are illegal to use on golf courses because they pose a threat to wildlife. Yet homeowners, not restricted by the same laws, apply more than 8 million pounds of diazinon per year to their lawns.

Lawn care based on chemical applications is pervasive in American residential communities, with staggering implications for the environment. Nearly 54 million pounds of pesticides and fertilizer are used every year to treat more than 21 million acres of residential lawns in the United States. These chemicals leach from the soil into groundwater, streams, lakes and oceans. In fact, the U.S. Geological Survey reported the presence of at least one commonly used lawn pesticide in 95% of stream samples collected nationwide in 1997. Such widespread use of chemical lawn treatments is polluting America's water supply and ecosystems, creating the likelihood of dire health consequences.

Chemical fertilization programs can be likened to “steroids for grass,” encouraging lush top growth that looks strong and healthy, but actually creating an unnatural, hydroponic subsistence on chemicals and water. In reality, the root systems of the grass, trees or shrubs are compromised because they are shallow. This condition makes the plants more susceptible to disease and pests, and even more likely to be treated with more chemicals, resulting in a downward spiral of chemical dependency.
Going organic provides a viable means to break out of the vicious cycle of chemical use and still attain that ever-elusive perfect carpet of grass. Organic approaches focus on plant health by nurturing the natural processes of plant growth and nutrient production. In contrast to the quick chemical fix that focuses only on leaf blade growth, organic fertilization literally feeds the naturally occurring soil organisms, providing nutrients as needed to help keep the whole, natural system in balance. With the natural grass defense mechanisms intact, the lawn is less susceptible to pests or disease, making chemical treatments unnecessary. Even weeds can be managed in this manner, with the possible exception of the hardy dandelion.

Simple Tips for a Healthy Lawn
Overseeding the lawn with high quality, disease- and insect-resistant grass seed promotes heavy grass growth and leaves no room for weeds to grow. Early fall is the best time to overseed, but it can be done with good results in late winter or early spring as well.

Proper mowing is also essential for a healthy lawn. Leaving the grass three to three and a half inches high helps to improve resistance to disease and weeds. Removing only the top third of the leaf blade per cutting helps grass roots to grow strong. Sharp mower blades ensure a clean cut with no ripping. Mow often and leave the clippings on the lawn, a simple method to return organic matter and nutrients to the soil.

Watering the lawn every day actually inhibits a strong root system. Watering once every three to six days with one half to one inch of water per application is adequate. Water in the early morning to avoid water that evaporates or is not absorbed.

Adding organic fertilizers such as com-post adds to the vitality and strength of lawns. Some organic choices available today are comprised of composted materials that nourish the soil and microorganisms, and encourage grass growth at a steady, even pace over the entire growing season.

The last step is to monitor pest problems, weeds or any disease conditions. If these do occur, there are treatment alternatives available that have no chemical additives. Natural predators can also be introduced to help control pests or certain disease issues. The most important thing to remember is that when problems do occur, solutions are available that do not entail covering the entire lawn with chemicals.

Achieving a beautiful, green lawn organically is really as simple as taking these few steps. Perhaps the best aspect of choosing an organic option instead of a chemical one is that environmental and health risks are eliminated, and your lawn can still look great.
